Objective/Background: Occupational therapy that focuses on servicing clients demands motivated workers for quality service delivery. The objectives of this study were: (a) to determine the level of work motivation among occupational therapy graduates in Malaysia and (b) to determine if there is a difference in work motivation among these graduates based on work sector, job position, length of work experience, and gender. Methods: This cross-sectional study recruited occupational therapy bachelor's degree graduates using an online survey. The Work Extrinsic and Intrinsic Motivation Scale (WEIMS) was used to measure level of work motivation. Results: Responses from 82 (60.3%) graduates (male: 26.8%; female: 73.2%) were analysed. Sixty-two (75.6%) graduates worked locally and 20 (24.4%) worked in foreign countries. The average Work Self-Determination Index (W-SDI) score for WEIMS is +11.38 with 78 (95.1%) of graduates demonstrated a self-determined motivational profile and 4 (4.9%) demonstrated a nonself-determined profile. Graduates in the private sector (13.10 ± 6.47) show significantly higher W-SDI score compared to those in the public sector (9.40 ± 6.06), p = 0.01. W-SDI scores appeared higher among clinician (11.67 ± 6.40), case manager (13.33), and others (14.90 ± 8.23); and those with work experience of 5–6 years (13.11 ± 6.90) and less than one year (12.65 ± 7.12). Male (10.29 ± 6.86) and female (11.79 ± 6.39) graduates shared equally high score. There is no significant difference in W-SDI score based on job position, length of work experience, and gender. Conclusion: Occupational therapy graduates have high work motivation as evident by their self-determined profile. Only work sector imposes difference in work motivation among these graduates.

Objective: To investigate the effects of pressure (Lycra) garment on the spasticity and function of the arm in the early stages after stroke. Design: A randomized controlled trial. Setting: Occupational therapy unit of a public hospital. Subjects: A total of 46 adults with stroke. Intervention: After random assignment, for six weeks, both intervention group and control group received a 2 hour/week conventional occupational therapy program, with the intervention group receiving an extra 6 hour/day pressure garment application (long glove). Main Measures: Modified Modified Ashworth Scale, Disabilities of Arm, Shoulder and Hand Outcome Measure, and Jebsen–Taylor Hand Function Test. Eligibility measures: Mini Mental State Examination and Modified Modified Ashworth Scale. Assessments were performed at baseline and six weeks postintervention. Results: There were 21 participants with the mean age of 51.19 (8.28) years in the intervention group and 22 participants with the mean (SD) age of 52.82 (8.71) years in the control group. The intervention group had median (interquartile range (IQR)) post-stroke duration of 1 (1) month, while for the control group, they were 2 (2) months. There was no difference in spasticity, and both perceived and actual arm functions between the groups at six weeks after baseline. Conclusion: Wearing a pressure garment on the arm for 6 hours daily had no effect in controlling spasticity or on improving arm function in the early stages after stroke.

Introduction: Purdue Pegboard Test (PPT) is a valid and reliable instrument for measuring hand dexterity among individuals with or without medical conditions. In the Southeast Asia region where Malay is widely spoken, there is a need to have a Malay translation of Purdue Pegboard Test. This study aimed to translate the PPT into the Malay version (PPT-M) and to determine the content validity and test-retest reliability of this translated version. Methods: This study involved: (1) four English teachers (translators) for forward and backward translation procedures; (2) 10 experts in the field of occupational therapy (expert reviewers) for content validity testing; and (3) 60 undergraduate students (participants) for test-retest reliability testing. Results: PPT-M had excellent content validity with Item-Content Validity Index = 0.9–1.0, Scale-Content Validity Index/Average = 0.93–0.95, and a slightly lower Scale-Content Validity Index/Universal Agreement = 0.25–0.75. Test-retest reliability for 3-trial administration ( n = 30; Intraclass Correlation Coefficients, ICCs = 0.76–0.85; good) was higher compared to 1-trial administration ( n = 30; ICCs = 0.34–0.46; poor) for all subtests. Both trial administrations were mostly affected by systematic errors, especially practice effect as the retests gave higher scores. Random errors mostly affected Subtest 3 of 1-trial administration, evident by its Minimal Detectable Change Percent values = 30.84% that fell beyond the acceptable range. Conclusion: PPT-M has the potential to be a valuable instrument for measuring hand dexterity among Malay speaking individuals especially when the 3-trial administration is used.

Background: Knee osteoarthritis (KOA) is a prevalent degenerative joint condition that impairs mobility and quality of life. While whole-body vibration training (WBVT) shows promise as an adjunct to conventional KOA rehabilitation, its efficacy remains unclear due to inconsistent clinical evidence. Objective: To elucidate the combined effects of WBVT and rehabilitation exercise on pain, physical function, and disability in KOA management through a systematic review and meta-analysis. Methods: A comprehensive search was conducted across eight electronic databases (PubMed, Web of Science, Embase, PEDro, SPORTDiscus, Scopus, ScienceDirect, and China National Knowledge Infrastructure) up to February 2024. Inclusion criteria were (i) randomized controlled trials comparing combined WBVT and rehabilitation exercise versus rehabilitation alone in KOA (ii) reported clinical outcomes (iii) human studies, and (iv) publications in English or Chinese. Trial quality was assessed using the PEDro scale and Cochrane risk-of-bias tool. The meta-analysis employed random-effects models in Review Manager 5.3 to account for heterogeneity, supported by sensitivity analyses for robustness and subgroup analyses on WBVT frequency effects. Results: Sixteen RCTs comprising 589 participants were included. The systematic review found that WBVT combined with conventional rehabilitation significantly reduced pain and improved physical function in KOA patients. The meta-analysis quantified these effects, showing that WBVT significantly (i) reduced knee pain (MD = −0.43, 95% CI [−0.70, −0.16], p = 0.002), with greater reductions observed from high-frequency WBVT, and (ii) increased isokinetic knee peak torque compared to rehabilitation exercise alone. No significant differences were found in balance, functional mobility, and disability outcomes. Sensitivity analysis of high-quality trials supported these results. However, the heterogeneity among studies and variations in control group interventions warrant cautious interpretation. Conclusion: WBVT seems to be effective in reducing pain and enhancing muscle strength in KOA patients when used in conjunction with conventional rehabilitation. Future high-quality RCTs must standardize WBVT protocols, emphasize long-term follow-up, and refine dosage for clinically meaningful outcomes.
